PAPER-BOX-COVERING MACHINE.

. Application led February 5, 1908.

To all 'whom t may concern: l

Be it known that' MARK D. KNOWLTON, late a citizen of the United States, and resident of Rochester, Monroe county, State of New York, now deceased, invented certain new and useful Improvements in Paper- Box-Covering Machines, of which the following is a specication. Y Y

This invention relates more especially to machines of that class adapted to apply a finishing exterior covering of paper to boxes made of paper or other material. In operating such machines it has proved necessary to control with a considerable degree of nicety the travel of the paper covering-strip on its Way from the pasting device to the form holding the box, in order to regulate the tack of the adhesive face of the paper, and for generally tempering the paper so that it may easily and quickly be laid smoothly upon the walls of boxes of various sizes held to the rotating box-form. y

ln prior machines of this class the pasted face of the traveling paper strip has run in Contact with one or more guide bars or rollers to which it was liable to stick if the machine were stopped for a time, and in again starting the machine there was liability or probability of tearing the paper in freeing it from the guides. Any over-quick movement of the traveling paper strip also was liable to loop it upon itself andbring pasted sides of the loop in contact, and efforts to straighten out these loops also incurr-ed'` liability of tearing the paper. Prior machines also did not give to the operator handling boxes at the form that prompt full View of the freshly pasted face of the traveling paper strip necessary to assure quick and proper regulation of the pasteV consistency or readjustment of the paste-applying device to maintain necessary uniform supply of paste to the traveling paper strip to assure proper tack of its adhesive, or to secure thorough tempering ofthe paper on its way from the pasting devices to the box on the form.

It is the more special object of this invention to practically obviate the above named disadvantages in simple and effective manner, while also making a machine much more compact than usual to save factory space, and one which may be safely run at maximum speed assuring economy Specification of Letters Patent.

of timepand labor in covering boxes of various sizes.

rlhe invention will first be described and then will be particularly deiinedin claims hereinafter set forth. l

Reference is made to the accompanying drawings forming part ofthis specification, and in which- Y Figure 1 is a side elevation of a box cov-` ering machine embodying a preferred adaptation of the invention. Fig. 2 is a front end view of the machine with the pasting device and paper reel omitted. 1Fig. 3 is an enlarged detail vertical section taken on the line 3-3 in'Fig. 1; and Fig.V 4 is an enlarged detail vertical section taken on the linel-ll in Fig. 1. i

To the main table or floor support 1 of the machine is adjustably held by a' leverclamping-nut 2, an arm 3 in which is journaled a shaft 4 carrying a box-form 5. The shaft 4 has a vworin-wheel 6 meshing with a Worm 7 on a shaft S which at its inner end has a bevel pinion 9 engaging a bevel gear Wheel V1() on a main driving shaft 11. Said shaftpl is rotated by 'any approved powertransmitting devices,'and the rotation and quick stopping of the box-form shaft 4L are controlled by the usual clutch and brake mechanism not necessary to show or de,- scribe. The shaft 4 also carries a cam 12 which operates va rod 13 to Which is coupled an arm 14- fixed to a rocking shaft 15.

(in this shaft 15 are two rigidly attached arms 1G, 16, supporting the movablev paper cutting blade 17 which coacts With a stationary cutter blade 18 held to a bracket 19 fastened to the table 1. Allk these briefly mentioned parts 1 to 19 may have'any approvedconstruction'as they form no part of the invention to be described.

To the table 1 is rigidly fixed a frame which may vary in details of construction but is shown formed oftwo opposite side parts each including front and rear brackets 20, 20, fixed to the tablel, and a horizontal bar 21 fixed in heads at the upper end of said brackets. Suitably supported by this frame betvveen'opposite bars 21, 21, 'are the paper-strip holdingV reel- 2,2and the paper-strip pastingV device, the latter comprising Va pasting roller 23 andV a paste-tanki 23. Fromthe reel and the pasting device y the paper covering-strip passes to a box'on the box-form over a Vseries of lntermedlate guides preferably made in the form of rollers and sustained by upright bars held to the frame; the said guides being supported and arranged in a manner to provide a strip-traveling circuit of adjustable length extending in a general direction around or about the pasting device and reel. In the drawings the paper-strip guiding rollers are shown sustained upon shafts held at one end only to brackets on upright rods supported at and from one side of the frame, but for certain classes of work it may be desirable to duplicate these rods and brackets at the other side of the frame to give support to the paper-strip guides at both ends, and this may be done at any time with little labor and expense.

Any desired number of paper-strip guides may be provided, but in the present case four main guides are provided, two of which are arranged in a vertical plane forward of the pasting device and reel and two in a vertical plane at the rear of said pasting device and reel. rEhe illustrated rod and bracket support for these guides will now be described. To the front frame bracket 20, is cast a lug in which is rigidly held a short vertical rod 24. @n this rod is held a bracket to which is fixed the shaft 26 of the lower front paper-strip guiding roller 27. The upper front paper-strip guiding roller 28 is journaled on a shaft 29 fixed to a bracket 30 which is vertically adjustable on a long rod 31. This rod 81 is fixed in a foot-block 32 pivoted on a pin 33 passed through a yoke or block 34 fixed to the projecting upper end of' the short lower rod 24 at one side of the machine frame. @ne end of the said pivot pin 33 is screw-threaded into one limb of the yoke 34, and the pin carries a hand-wheel 35 by turning which the yoke limbs may be caused to clamp or release the foot-block 32. This construction permits the rod 31, with the supported upper roller Q3, to be bodily Vinclined either forward or backward on the pivot 33 and then clamped by the wheel 351 in any desired position. On the overhang ing rear end of the same side-bar 21 is mounted a collar 36 having a bearing lug 37 in which is fixed a short pendent rod 38 on which is mounted a vertically adjustable bracket 39 carrying the shaft 40 of the lower rear paper-strip guiding roller 42. T he upper rear paper-strip guiding roller 41 is journaled on a shaft 43 fixed to a bracket 44 which is vertically adjustable upon a long rear rod 45 like the front rod 31, and like it supported in a foot-block 32 pivoted in a yoke 34 which here is fixed to the projecting upper end of the short rod 38. A. handwheel 35 provides for clamping the rear rod 45 at anyy desired adjustment on its pivot substantially as the rod 31 is held, and as will be understood from enlarged Fig. 4 of the drawings. All of the said guide holding brackets are held at any required adjustments on and along their respective rods 31, 38, 45, by a set-screw 4G, sucli as Ashown in enlarged Fig. 3 of the drawings.

n the operation of the machine, the paper covering-strip, indicated at 50, passes from the reel 22 over the paste-applying roller 23 against which it is held by guides 51, 5:2, while a scraper 53 located in advance of the roller 23 and forming part of the pasting device operates to remove surplus paste from the pasted face of the traveling strip. Should the strip already be adhesive, the roller 23 will apply water to meisten said adhesive in well known manner. From the pasting devices the paper-strip passes forward and upward over the lower front guide-roller 27 and to the upper front guideroller 28, whence the paper passes rearward above the pasting device and the paper reel to the upper rear guide roller 41, and thence downward to the lower rear guide roller whence the paper passes forward below the reel and the pasting device and between the open cutters 17, 18, to the operator who applies it smoothly upon a box 54 held to the rotating form 5. The movable cutter-blade 17 descends at proper time to sever the requisite length of paper to cover a box of any size held to a proper form 5 rotated by the shaft 4. immediately the paper-strip is severed by the cutters the unwinding of the strip from the reel 22 ceases and the adhesive end of the paper resting on the lower iixed cutter 1S will cling thereto or to the cutter rocking shaft 15, sufficiently to prevent fall of the lower portion of the paper-strip which thus will be lightly held until it is removed by the operator who will draw the paper-strip forward again and apply its end to the next box which then begins its rotation for laying the paper-strip upon it.

Should it be desired to more or less vary the distance of' movement of the paper-strip in transit between the pasting devices and the box-form, this may be quickly and easily done by loosening the clamping-blocks et the rods 31, 45, and then swinging these rols on their pivots 33 either toward or from each other, as indicated by the dotted lines in l of' the drawings. `When thus adjusted the bars will be locked in adjusted position by turning the wheels 35. Either one or both of the rods 31, 45 may thus be adjusted, and the upper guide rollers 23, 41 may also be bodily adjusted to any desired position along the rods 31, 45 and re-fastened by the setscrews 46; all as the condition of' the paste in the tank 233er as atmospheric conditions, or as the size of the boxes to be covered, may require to obtain necessary distance of travel of the paper between the pasting devices and he box-form for maintaining proper tack of the paste or adhesive, and for assuring adequate tempering of the paper for prothe paper-strip over guides from the pasting device to the cutter and box-form or other means utilizing the adhesive paper, said paper is so conducted that its pasted or adhesive face is always at the outside, and its unpasted or non-adhesive face is always at the inside, and only this non-adhesive face of the paper is in contact with the guides whether these be the preferred illustrated rollers, or be rods or slats. It

follows that there can be no sticking of the paper to the guides and subsequent troublesome separation of it therefrom; and should the paper accidentally loop upon itself the inner unpasted faces of the loop would come in contact and could not stick together and later require separation. Danger of tearing thepaper from these two causes, as in using prior machines, thus is entirely obviated.

' Another important feature is the conducting of advancing portions of the paper-strip just leaving the pasting device, in such manner that the freshly pasted face of the paper-strip is always near to and in full view of the operator handling boxes at the form, and who thus without effort or loss ofl time may always see that the paste is in proper condition and that the laying of the paste upon the paper is effected evenly over its entire area. prevail, the operator has early opportunity to stop the machine and correct any irregu- I larities of working in these respects, thereby avoiding loss of time and paper stock and promoting the most satisfactory tempering of the paper and its easy and smooth laying on the boxes.

A third important feature is conducting the Y pasted paper-strip both above and below the pasting device during transit of the paper from this device to the box-form or place of utilization, or conducting the 'paper-strip above and below both the pasting device and the paper reel when the reel is sustained in the preferred illustrated manner directly behind the pasting device. This operative feature permits making the entire machine very much shorter than prior machines of this class, thus saving valuable factory space and making the machine lighter and less expensive to build. Should the reel be supported above the pasting device, or on the Hoor, or should it be sustained entirely to one side of and independently of the kma- Should these conditions not Y chine, as might be done,the machine may be made even shorter than is shown in F ig. l of v the drawings, without materially sacrificing the possible range of variation in length .of that portionv of the paper strip to transmit between the pasting device and the boxform or other paper utilizing means.

Various modifications may be'made in. thisl invention within the scope of any one or more of the appended claims, and as above intimated, the invention is-not limited to apparatus specially designed for covering boxes placed upon a rotating'form, but may be embodied in other apparatus for or methods of utilizing an adhesive paper sheet.
